Hi , i can't use this variable
I need , to go on a purge zone , and to blip the fan to full power , and after purge , to set the old value of fan speed
I make this
M106 S255
Purge ....
M106 S[fan_speed_pwm] or percentage
and in the gcode , i don't have a number value , i have this M106 S[fan_speed_pwm] , written like this
I use marlin/repetier flavor
Do you have a solution ?
THks
